EASY FUDGE BROWNIE ICE CREAM 🤎 (recipe below) the EASY FUDGE BROWNIE ICE CREAM 🤎 (recipe below) the easiest no-churn chocolate ice cream with gooey brownies + ribbons of fudge in every bite!! Even if you’ve never made ice cream before, you’ll be amazed at how easy this is to make without an ice cream maker 

🍦Full recipe at https://sugarandsparrow.com/no-churn-fudge-brownie-ice-cream/ + more no-churn ice cream recipes linked in my bio 

INGREDIENTS
2 cups (480ml) heavy whipping cream, cold
3/4 cup (4oz, 135g) semi-sweet chocolate chips
14 oz sweetened condensed milk
1/3 cup (30g) cocoa powder 
1 tsp vanilla
pinch of salt
2 cups brownie chunks (store bought or homemade) 
6 oz hot fudge sauce

INSTRUCTIONS
1. In a large chilled bowl, beat the heavy whipping cream with a hand mixer (or stand mixer w/ whisk attachment) until stiff peaks form, about 2-4 minutes. Place into refrigerator.
2. Heat the chocolate chips in the microwave in 30-second increments, stirring after each one, until melted and smooth.
3. In a separate medium bowl, whisk together the sweetened condensed milk and melted chocolate, then whisk in the cocoa powder, vanilla, and salt. 
4. Fold 1 cup of the whipped cream into the chocolate condensed milk mixture. Then, pour the chocolate mixture into the remaining whipped cream and fold together until combined. Fold in the brownie chunks. 
5. Scoop large spoonfuls of the brownie ice cream mixture into a loaf pan along with a few smaller spoonfuls of the hot fudge sauce. Use a wooden skewer or butter knife to swirl the hot fudge and create ribbons as you go. Continue adding and swirling until all of it is in the loaf pan.
6. Press the reserved brownies into the top of the ice cream, then cover with plastic wrap or aluminum foil. Freeze for 6-8 hours, after which the ice cream should be semi-firm, scoop-able, and ready to enjoy!
